To aZZ whom it may concern:

Be it known that I, VERN C. BARTLETT, a citizen of the United States, residing at Joplin, in the county of Jasper and State of a Missouri, have invented new and useful Improvements in Baths or Flux for Prevent- .ing Corrosion or Busting of Motor-Vehicle Wheel Rims and l/Vire Wheels, of which the following is a specification.

The object of my said invention is the provision of an economical and eilicient bath or flux for treating wheel rims that carry rubber tires, whereby the formation of rust on said rims is effectively prevented.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the best practice of my invention of which I am cognizant I first boil the rim, 20 demountablerim, or the wire wheel in a strong solution of caustic soda, this to eliminate paint, rust and the like therefrom. I then scrub the rim or wheel, and rinse the same to remove all alkali. The rim or the wheel is then immersed in commercial muriatic acid with a view to effectively remov ing therefrom all foreign substance. The rim or the wheel is then placed in a bath or flux composed of the following ingredients combined in substantially the proportions stated, viz:

Percent. Zinc chloride 48 Glycerine 4 5 Zinc sulfate 2 Water (distilled) 46 The rim or the wheel is let remain in the bath or flux defined for an appropriate to period of time, after which the rim or the wheel is removed from the bath and is Application filed September 12, 1922. Serial No. 587,810.

quickly thereafter immersed in pure molten tin (preferably block tin). In this way the rim or the wheel will be uniformly and smoothly coated with tin which in virtue of being fiuxed on by the bath defined will strongly adhere to and will not scale or flake oil with the result that the rim or the wheel will. be permanently and adequately protected against rust or corrosion. 5 In the case of wire wheels, the described coating oftin also serves to permanently set the spokes so that loosening of the spokes will be precluded. I would also have it understood that when deemed expedient cop- ..per filings may be mixed with the pure tin for the coating of wire wheels in order to impart an attractive golden or bronze color to the wheels.

My improvement as hereinbefore set so forth is not to be confounded with the use of zinc on automobile and aeroplane wheel rims, zinc because of its hardness. being liable to oxidize and flake ofi' whereas tin because of its soft quality will give to vie5 bration andshock and bends and will adhere to the metallic parts that it covers and protects.

Having described my invention, what I claim and desire to secure by Letters Patent, is I 1. A solution for the purpose described consisting essentially of zinc chloride, glycerine, zinc sulfate, and Water.

2. A solution for the purpose described consisting'essentially of zinc chloride, glycerine, zinc sulfate, and water; zinc chloride 48 per cent, glycerine, 4 per cent, zinc sulfate, 2 per cent, and water 46 per cent ln testiinony whereof,'I aflix my 'signature. I
